v INC., AUBURN, YORK, A CORPORATION NT oFF c E ASSIGNOR FORM 00., OF NEW YORK BACK-PART STAY Application filed June 11,

. This invention relates to an improvement in back part stay for shoe forms such as is shown for example in my copending applica tion, Serial No. 265,000. filed March 27, 1928. 5 As shown in the copending application the back part stay is attached at its forward end i to a toe form and bears at its rearward end against the heel counter of the shoe.

The primary object of the present inven- 30 tion is to provide a back part stayprovided with a loop at its rearward end, which loop is so constructed that the body of the back part stay will bend freely upwardly and hold the toe form yieldingly in its position in the shoe.

Another object of this invention is to provide a back part stay provided at its rearward end with a closed loop which is integral with the body of the stay and which is quickly and so easily formed and closed by following the present invention.

A further object of this invention is to provide a back part stay which is covered to a considerable extent with fabric of a color chosen so that the stay will present a pleasing appearance when inserted in a shoe. Other objects of the invention will appear from consideration of the following specification taken in connection with the drawings,

: in which a Fig. 1 is a side elevation of a completed back part stay embodying this invention;

Fig. 2 is a similar View of a back part stay before the rearward loop has been completed;

Fig. 3 is a view illustrating one step in the preparation of the loop;

Fig. 4; is a sectional view taken line 44 of Fig. 3;

Fig. 5 is a sectional view taken substantially along the line 55 of Fig. 1 and illustrat-ing the loop before the final operation is performed; and

Fig. 6 is a side elevation of a portion of a completed back part stay upon which fabric has been applied.

The function and purpose of the back part stay to which this invention applies is clearlyshown and set forth in my copending application above mentioned and also in my Patent No. 1,646,016, dated October 18, 1927. In

along the is drawn back until'it tube 10 and is then released the notch 17 re- 192E).v Serial No. 370,028.

view of this disclosure it is believed unnecessary to illustrate the manner of using a shoe form provided with a back part stay or to show a form and back part stay inserted in a shoe.

The back part stay 10 is preferably made of celluloid or similar material in tubular form and in order to supplement the resiliency of the material forming the stay a thin length of wire 11 is usually inserted into the hollow of the tube.

vided at its front end with an integral loop 12. .The wire and tube are assembled when bined is then oii'set to form an incomplete loop 15 and the forward endofthe wire 11 is provided with an integral loop 12. Y It will be noted that the end 16 of the loop 15 extends This wire 11 terminates short of the rear end of the tube and is proacross the body of the tube, as shown in Fig. 2, when thetube and wire are bent and that the wire 11 terminates ata considerable distance from the end ofthe tube. In order to completethe looploit is necessary that the enl 16 be rigidly united to the body of the tu e. l a

The preferred procedure to be followed in uniting these members is particularly shown in Figs. 3, 4; and 5 wherein itwillbe noted that the end 16 is provided with a V -shaped notch 17 formed by subjecting it to an emery wheel'lS or similar cutting device. After the notch 17 has been formed the end 16 passes the body of the ceivin the body of the tube 10 and by reason of its form holding the end 16 in position without needof particularfattention. Other means for forming the notch 17 may be em .ployedand such notchneed not necessarily jbelV-shaped. This featureof the invention is preferably that v the end 16 shall be so treated that ithas a secure engagement with c the body of the tube such that it will automatically remainin contact therewith. Tl end 16 is then treated with acetone or similar adhesive and is quickly welded or rigidly united to the body of the tube.

' lVhile the tube 10 may be made of any desired material and of any color it has been found that in many instances the celluloid of the back part stay can not supply the color, which will correspond to or form a pleasing contrast to the color ofthe shoe in which the shoe form including the back part stay is to be'inserted. Accordingly the body of the back part stay is covered with a fabric 20 of the desired color which is preferably tubular and slipped over the body of the tube before the end 16 is secured thereto. The acetone or other adhesive by which the end 16 is secured to the body 10 will function equally well even if the fabric 20 is in place. In place of so securing the fabric 20 it may be attached directly to the stay tube by touching the end or any part of it with acetone or a similar adhesive so that it will be readily fixed in place.

It has been found particularly desirable to dress the shoe by covering the stay with a shoe lacing of the same color as the lacings used in the shoe. It will be noted that the loop 15 is offset from the main body portion of the tube which is unbent and that the end 16 of the loop, tends to direct the tube upward directly away from the heel counter. The loop 12 is similarly offset and consequently the back part stav forms a smoothly continuous curve from the toe to the heel counter.

While I have described one form of tube and one method of completing the loop 15 I am not limited thereto since other improve ments might be made without departing from the spirit and scope of this invention as set forth in the following claims;

I claim:

1. A back part stay for a shoe form comprising a tube of celluloid or similar material, and a resilient wire inserted into the hollow of the tube, one end of the wire projecting from the tube while the other end is encased. the ends of the back stay being formed into loops both offset from the body of the stay in the same direction.

2. A back part stay fora shoe form comprising a tube of celluloid or similar material, and a resilient wire inserted into the hollow of the tube, said tube terminating at its outer end in a loop'offset from the body of the tube, the end of the loop being rigidly united to the body of the tube. 3. A back part stay for a shoe form comprising a tube of celluloid or similar material, and a resilient wire inserted into the hollow of the tube terminating at its outer end in a loop offset from the body of the I tube, the end of the loop being provided with a depression which receives the body of the tube thus yieldingly holding the parts in contact.

4. A back part stay for a shoe form comprising a tube of celluloid or similar mate- I rial, and a resilient wire inserted into the hollow of the tube terminating at its outer end in a loop offset from the body of the tube, the end of the loop being provided with a V-shaped notch which receives the body of the tube thus yieldingly holding the parts in contact.

5. A back part stay for a shoe form comprising a tube of celluloid or similar material, and a resilient wire inserted into the hollow of the tube, said tube terminating at its outer end in a loop offset from the body of the tube and a fabric covering the body of the tube and firmly attached thereto at said loop.

6. The method of forming a loop at the end of a back part stay for shoe forms which stay includes a tube of celluloid comprising the following steps, bending the portion of the tube to form the loop so that the end extends across the body of the tube, forming a depression'inthe end, assembling the end with the body of the tube, the latter resting in the depression and uniting the contacting surfaces by adhesive.
